To a/ZZ whom t may concern,.-

Beit known that I, OSCAR H. R. SGHULZE, a citizen of the United States,residing at 210 Dearborn avenue, Chicago, Illinois, have invented a newFire-Arrester for Electric-Incandescent-Light Wires, of which thefollowing is a specification.

The object of my invention is to prevent fire originating at the globeor socket ot' an electric-incandescent-light wire trorn spreading byfollowing along the cloth-covered wire.l

Figure 1 is a perspective View of my invention complete. Fig. 2 is adetail perspective view.

Fig. l shows the invention complete and ready for use.

Fig. 2 shows two blocks of asbestos, each about two inches long by aboutone inch Wide and about one-half inch thick, and each block having twogrooves on one side about one inch apart and about one-sixteenth of aninch in depth extending the Whole width of the blocks of asbestos,sothat when the blocks are placed with their grooved sides together theyform a clamp closely itting to and inclosing the two strings of anelectric-incantiescent-light Wire, which strings have been separated orspread apart sufficiently to fit in the grooves in the blocks ofasbestos. The two blocks of asbestos when so itted around the twostrings or wires are held together by a band of tin or othermetal'(marked c, Fig. l) which surrounds the blocks and is placed atabout the middle of the tlat sidesthereof. The letters a and ZJ showends of blocks of asbestos.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is

The two blocks of asbestos, each having two grooves extending across oneside, into which the two strings of an electric-incandescent-light wirewhich have been spread apart sufficiently to iit in the grooves, havebeen placed, and the two blocks of asbestos with their grooved sidestogether, then tightly clamped to the wires by a metallic band, to fornia complete barrier to ame or tire, and to prevent it from following theWire and burning beyond the point where the asbestos Witnesses:
